Yes, Your Dirty Windows Could Be Making You Sick

Routine window cleaning can help offset airborne infections and decrease your risk of allergies.

Did you know that experts estimate that there are approximately 8,000 types of bacteria inside the average home? Your windows have a lot to do with that. Bacteria and allergens tend to live on window surfaces longer because they’re not routinely cleaned. This means your dirty windows could make you sick because you end up breathing in whatever’s on your windows, whether it’s dust, mold, or an airborne disease. Fortunately, regular window cleaning can help prevent this.

Here are the most common types of bacteria and allergens on your windows that might be making you sick:


Anywhere there’s mold, there’s always a risk of allergies and other respiratory conditions. Generally, windows are where hot and cold air meet. This causes condensation, which – if not cleaned up right away – can turn into mold. Unfortunately, mold can trigger allergies and worsen conditions like asthma. If you’re constantly sneezing or experiencing headaches, mold from your dirty windows could be to blame.

Regularly cleaning your windows and window frames is the best way to prevent mold from developing. If you notice a continuous buildup of condensation around your windows, invest in better windows with a stronger frame.

Airborne Infections

Airborne infections like the flu can stay on non-porous surfaces for up to 48 hours. This means that whatever infection you or your family unwittingly bring into the house could live on the surface of your window. This applies to other airborne pathogens, as well as COVID-19. Since this is an airborne infection, studies have shown that it can stay on the surfaces inside your home for up to three hours. However, this also depends on your home’s temperature and humidity level.


Dust is another common type of bacteria that lives on your window surfaces. Like mold, dust can trigger allergies. However, it can also cause dust mites. Dust mites are tiny bugs that feast on human skin cells in the dust. Dust mites can be commonly found in upholstered items, like your curtains. Routine window cleaning removes dust, which simultaneously removes their source of food.

Unfortunately, dust mites can cause persistent coughing, sneezing, and watery eyes. Like mold, dust can also make asthma worse and cause someone to suffer an asthma attack. Furthermore, prolonged exposure to dust may cause some people to develop a lung disease called hypersensitivity pneumonitis. This is an immune system disorder that causes inflammation in the lungs.
